Marconi, California
Marconi is an unincorporated community in Marin County, California. It is located on the northeast shore of Tomales Bay, about seven miles south-southeast of the village of Tomales, at an elevation of about 70 feet above sea level. Marconi is located in the area of the town of Marshall, California.
The inhabitants of an old Native American settlement called "Fisherman's" later shipped seafood from here via railroad. Then, in 1913, the Marconi Wireless Company bought this site to establish a transpacific wireless telegraph station.
